Given:

In a right angle triangle ABC, [tex]m\angle B=90^\circ, BC=x, AC=11, m\angle C=41^\circ[/tex].

To find:

The value of x to the nearest tenth.

Solution:

In a right angle triangle,

[tex]\cos\theta =\dfrac{Adjacent}{Hypotenuse}[/tex]

In the given right angle triangle ABC,

[tex]\cos \angle C =\dfrac{BC}{AC}[/tex]

[tex]\cos (41^\circ) =\dfrac{x}{11}[/tex]

[tex]11(0.7547) =x[/tex]

[tex]8.3017 =x[/tex]

Round the answer to the nearest tenth.

[tex]x\approx 8.3[/tex]

Therefore, the value of x is 8.3 units.

Answer:

Step-by-step explanation:

1) take a better picture next time

2) Add 70+90= 160 then 180-160= 20 to find the last angle

3) tan20= x/20

4) x= 7.27

Answer:

25%

Step-by-step explanation:

The 5 values of the given box plot are;

The minimum value = 20

The first quartile, the 25th percentile point, Q₁ = 25

The median or second quartile, the 50th percentile point, Q₂ = 30

The third quartile, the 75th percentile point, Q₃ = 40

The maximum value = 55

The range = The maximum value - The minimum value

∴ The range = 55 - 20 = 35

We note that Nicholas earned $25 or less from the minimum value up to first quartile, Q₁, which is the 25th percentile point, where we have 25 percent of the data points

Therefore, the percent of the time Nicholas earned $25 or less is 25 percent of the time.

Answer:

1. 0.0469 (4.d.p)

2. 0.05

Step-by-step explanation:

1. First we'll find the probability of drawing a blue marble.

P = (No. favourable events)/(Total events)

In this case it's:

P = (No. blue marbles)/(Total Marbles)

Therefore P(Blue) = 4/16 = 0.25

Now we find the probability of drawing a yellow marble:

The total number will be the same because the blue marble will have been put back.

P(Yellow) = 3/16 = 0.1875

Now, since we are calculating the probability of both happening we multiply together the two individual probabilities to get the combined probability of both:

0.25 x 0.1875 = 0.0469 (4.d.p)

2. The probability of drawing a blue marble is still the same so we can keep that: P(Blue) = 0.25

But this time, the marble is not replaced. This means that the total number of marbles has changed when drawing the yellow marble:

P(Yellow) = 3/15 = 0.2

Now we multiply them together again to find the combined probability of both happening:

0.25 x 0.2 = 0.05

Hope this helped!

Answer:

7 and 12

Step-by-step explanation:

x - y = 5

y = (5+x)

x+ (5+x) = 19

2x +5 = 19

2x = 14

x = 7

           19-7 = 12

12 +7  = 19

12-7 = 5

Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the smallest:

[tex]\frac{1mi}{5,280ft} =\frac{3mi}{xft}[/tex]

Do butterfly method and you should get this:

[tex]xft=3(5280)\\x=15,840ft[/tex]

Setup proportion to solve for the largest:

[tex]\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}[/tex]

Butterfly method:

[tex]xft=3.2(5280)\\x=16,896ft[/tex]

Answer: primary waves

Step-by-step explanation: pressure waves that travel faster than other waves through the earth to arrive at seismograph stations first, hence the name "Primary". These waves can travel through any type of material, including fluids, and can travel nearly 1.7 times faster than the S-waves.

Answer:

I would go with plan b because $0.05 can add up pretty fast and would be more expensive than $28

Answer:

32

Step-by-step explanation:

count each cube and it equals 32

The ladder and the top of the building form a right triangle

The building is 20.8 feet tall

The given parameters are:

The height (h) of the building is calculated using the following Pythagoras theorem

L^2 = b^2 + h^2

So, we have:

39^2 = 33^2 + h^2

Evaluate the exponent

1521 = 1089 + h^2

Rewrite as:

h^2 = 1521 - 1089

h^2 = 432

Take the square root of both sides

h = 20.8

Hence, the building is 20.8 feet tall

The answer to this question is 65

Answer:

65°

Step-by-step explanation:

180-50

=130

130/2

=65°

the other side is also 65 ° because this is an isosceles triangle.

I need help with this too it’s confusing and I don’t understand it.

Answer with step-by-step explanation:

Let us find the perfect cubes between 1 to 100.

We know that, 1

3

=1,2

3

=8,3

3

=27,4

3

=64 and the rest numbers i.e. 4,5,6,.... have their cubes greater than 100.

So, only these four numbers have their cubes between 1 to 100.

Thus, there are 4 perfect cubes from 1 to 100.

Now, let's find the cubes between −100 to 0

We know, 0

3

=0,(−1)

3

=−1,(−2)

3

=−8,(−3)

3

=−27,(−4)

3

=−64 and the rest numbers have their cubes less than −100

So, only these 5 numbers have their cubes between −100 to 0 and 4 perfect cubes are there from 1 to 100.

Thus, there are 9 perfect cubes from −100 to 100.

Step-by-step explanation:

Since C is 48 you minus 6 from it since 6 is on the side so thus 48 - 6 = 42

Happy I can help

Answer:

48

Step-by-step explanation:

We are going to use trigonometry to solve for the wanted angle

Remember these are the trigonometric functions

( Remember SOH CAH TOA )

Sine = Opposite over Hypotenuse (SOH)

Cosine = Adjacent over Hypotenuse (CAH)

Tangent = Opposite over Adjacent (TOA)

For angle Ф

we are given its adjacent side length (6) and the hypotenuse (9)

Adjacent and hypotenuse corresponds with the trig function Cosine

So we will use cosine to solve for the missing angle

( let x = missing angle )

( remember cosine = adjacent over hypotenuse )

[tex]cosX=\frac{6}{9} \\\frac{6}{9} =.66\\cos(x)=.66[/tex]

now we want to get rid of the "cos" on the x

To do so we take the inverse of cos ( arc cos ^-!1 ) and apply it to each side

so...

[tex]arcos(cos(x))=x\\arccos(.66)=48.1[/tex]

we're left with x = 48.1

Answer:

A. 2^4 . 2^-3 . 2^4 . 2

Step-by-step explanation:

Option A,

2^4 . 2^-3 . 2^4 . 2

= 2^4 . 2^-3 . 2^4 . 2^1

= 2^( 4 + 4 + 1 - 3 )

= 2^( 9 - 3 )

= 2^6

= 64

So, Option A is the correct answer.

Answer:

(7,4)

Step-by-step explanation:

Midpoint Formula = [tex](x_{1} + x_{2}/2)=[/tex] x coordinate of midpoint

same for y coordinate of midpoint

so

2=-3+x/2

4=-3+x

x=7

for y

5=6+y/2

10=6+y

y=4

therefore B(7,4)
